Node.js vs. Geddy vs. Padrino

Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

Geddy is a full stack open source MVC framework based on ruby on rails methodology with built-in authentication module, passportjs and socket.io integration.

Padrino is a ruby framework built upon the excellent Sinatra Microframework. Padrino was created to make it fun and easy to code more advanced web applications while still adhering to the spirit that makes Sinatra great!
